RE: Only 16% of new UK cars (Pure Electric) contain no PGM catalytic converter!6 Feb 2024 12:46
I asked Bing if PGMs are used in batteries and got the following reply:
Certainly! Platinum group metals (PGMs) are indeed utilized in lithium batteries, particularly in the pursuit of more efficient and advanced energy storage technologies. Here are some key points:
Lithium Batteries and PGMs:
Platinum group metals (which include elements like platinum and palladium) play a crucial role in enhancing battery performance.
These metals are used as catalysts within the battery system, specifically in the cathodes.
The goal is to improve rate capability (how quickly the battery can charge and discharge) and reduce the charge over potential.
PGMs contribute to the stability and efficiency of lithium batteries.
Recent Developments:
Platinum Group Metals (PTM) and its subsidiary Lion Battery Technologies have been at the forefront of this research.
Lion Battery Technologies was established by Anglo American Platinum (Amplats) and PTM to accelerate the development of next-generation battery technology using platinum and palladium.
The US Patent and Trademark Office has issued a second patent to Florida International University (FIU) related to the use of PGMs in lithium batteries.
The patent covers a preparation method using PGM catalysts in carbon materials for cathodes in various lithium batteries, including lithium-ion, lithium-air, and lithium-sulfur batteries1.
Potential Applications:
PGM-enhanced batteries have the potential to significantly improve the performance of battery electric vehicles (BEVs).
Additionally, PGMs find applications in other green technologies, such as cleaner emissions equipment for internal combustion engines and hydrogen fuel cell power generation in cars and trucks12.
In summary, PGMs are making strides in battery technology, aiming to create more efficient and sustainable energy storage solutions. 🚗⚡🔋
If this is correct, then regardless of the type of vehicle PGMs will be required. How much of each metal there would be in each type of vehicle is not clear from the above, but electric vehicles contain large numbers of cells so intuitively one might expect them to need more than trace amounts. In addition, there are various battery storage schemes being developed to support electricity generation projects. This suggests the future might be brighter than the market is currently suggesting.
